Water analysis at SANA, the international Biological and Natural Exhibition
H2O is the molecular formula of water, formed by two atoms of hydrogen and one of oxygen, and we can consider it pure / distilled in the rain. On the ground and in the subsoil water naturally enriches itself with many substances, mineral salts, ions and other elements as it acts as a solvent: as happens daily when we dissolve salts, sugars, chlorine, carbon dioxide and other solids / liquids / gases in water. The usefulness of the substances dissolved in water is a function of their concentration to the point of becoming harmful to humans, animals, crops and the environment.
Before using water it is important to know its characteristics and the quantity of substances dissolved in it.
